In Wickard v. Filburn, the Supreme Court upholds the Agricultural Adjustment Act of 1938, which restricts the total amount of wheat a farmer may produce. Secretary of Agriculture Claude Wickard fines farmer Roscoe Filburn for producing in excess of the maximum. Filburn contests that the wheat he sold on the market was within the limits set by the law and that the rest was used for personal consumption. The Court finds that the combined impact of individual farmers removing themselves from buying wheat on the market could destabilize the national wheat market and that their production must therefore be restricted.
